Description
- systemd-networkd autoupdated to 252.39-1~deb12u2
- this caused the guest-agent added routes to the local routing table to get removed
- NLBs targeting the impacted VMs started failing healthchecks and couldn't deliver traffic to the VMs
- a manual restart of `google-guest-agent.service` was required to fix networking
guest-agent should either chain a restart from networkd or actively reconcile routes?
